Referring to fig. 1 to 5, a further method, which analyzes the structure of the machining model, is shown: in step two, a machining surface which is relatively independent in the Z-axis direction in the machining surfaces of the machining model is taken as a layer surface, and the layer surface defining the top surface of the machining model is taken as a layer surface 0, that is, a layer surface 0= (x 0, y0, Z0), coordinate data of all the layer surfaces are obtained and stored in a storage terminal, and the Z-axis coordinate value of any layer surface is compared with the Z-axis coordinate value of the adjacent layer surface:
if the Z-axis coordinate values of the bedding plane are all smaller than the Z-axis coordinate values of the adjacent bedding plane, judging that the boundary of the bedding plane and the adjacent bedding plane around form a frame-shaped structure;
if the Z-axis coordinate values of the layer are all larger than the Z-axis coordinate values of the adjacent layers, judging that the boundary of the layer and the adjacent layers around form a convex structure;
if the Z-axis coordinate value of some adjacent layers is greater than that of the layer and the Z-axis coordinate value of the other adjacent layers is less than that of the layer, it is determined that the layer and the adjacent layers form a frame-like slot structure.
Specifically, in the operating system (powerlimit), the default XY plane is parallel to the horizontal plane, the Z axis is perpendicular to the horizontal plane, the machining surface of the obtained machining model is arranged upward, and the outer contour of the whole machining model is arranged in a cube shape. In order to analyze the structure of the processing model so as to obtain a cavity structure in the processing model, a plurality of relatively independent processing surfaces of the processing model are named as layers along the Z-axis direction, and the height of the adjacent layers is judged through judgment so as to know the structural relationship between the layers and the adjacent layers: the convex type, the frame type and the groove type with the opening achieve the structure corresponding to each layer, so that the subsequent matching with the processing technology in the processing technology library is facilitated, and the corresponding processing technology program is obtained.

when z0-zt =0, the layer corresponding to the convex structure is the top surface of the processing model, and a frame-type or groove-type structure is not formed between the layer corresponding to the convex structure and the layer 0 of the top surface of the processing model;
when z0> zt, there is a distance between the level corresponding to the male structure and level 0, i.e., a corresponding frame or trench structure is formed between the level corresponding to the male structure and level 0.
Specifically, the Z-axis coordinate value of the corresponding layer of the convex structure is compared with the Z-axis coordinate value of the layer 0, so that the height between the corresponding layer of the convex structure and the layer 0 of the top surface of the processing model is obtained, and whether the corresponding frame or groove structure can be formed between the corresponding layer of the convex structure and the layer 0 is judged.

Specifically, in the process, all coordinate data on an XY plane in the outer contour of the machining model are obtained and defined as a coordinate library for storage, and then are compared with X-axis coordinate values and Y-axis coordinate values of all the coordinate data in a storage end, so that coordinate data which are not overlapped with coordinate values of any point in a layer on the XY plane in the coordinate library are obtained, a plurality of coordinate data can form coordinate data of the same continuous plane in the XY plane as a set and are named as units, the boundary of each unit is the shape profile of a corresponding through hole or through groove structure in the machining model, and the machining depth of the through hole or through groove structure formed by each unit is the whole thickness of the machining model.
Referring to fig. 1 to 5, a further method for obtaining the machining depth of each cavity structure includes: defining the Z-axis coordinate of the layer corresponding to the frame-shaped structure as zk, defining the Z-axis coordinate of the layer corresponding to the groove-shaped structure as zc, and then acquiring the depth data of the corresponding cavity structure:
when the layer corresponding to the convex structure acquired in the step two does not coincide with the layer 0 of the top surface of the processing model, subtracting the Z-axis coordinate value zt, namely Z0-zt, of the layer corresponding to the convex structure of the layer from the Z-axis coordinate value Z0 of the position of the top surface of the processing model, and acquiring the maximum value of the processing depth of the layer corresponding to the convex structure and storing the maximum value to a storage end;
subtracting the Z-axis coordinate zk of the layer corresponding to the frame-shaped structure from the Z-axis coordinate value Z0 of the top surface position of the machining model, so as to obtain the maximum value of the machining depth of the layer corresponding to the frame-shaped structure, and storing the maximum value in a storage end;
and subtracting the Z-axis left side of the layer corresponding to the groove-shaped structure from the Z-axis coordinate value Z0 of the top surface position of the machining model, so as to obtain the maximum value of the machining depth of the layer corresponding to the groove-shaped structure, and storing the maximum value to a storage end.
Specifically, because the layer has the inclined plane, the Z-axis coordinate values of the layer corresponding to the convex structure, the layer corresponding to the groove structure, and the layer corresponding to the frame-shaped layer are respectively defined as zt, zc, and zk, and then compared with the Z-axis coordinate value of the layer 0, so as to reach the maximum value of the corresponding processing depth, and thus, the corresponding effective processing tool can be effectively selected for processing.
Referring to fig. 1 to 5, a further method for selecting a machining tool according to the machining depth of the cavity structure is as follows: arranging a plurality of cutters in the processing cutter base information into a cutter base table according to the length priority order, and defining the cutter base table as Tlist1= { T1, T2, T3, T4, … and Tn }; according to each obtained maximum machining depth, selecting a plurality of cutters with the lengths larger than the maximum machining depth in the machining cutter base information as machining cutters of the machine tool, listing the plurality of machining cutters corresponding to the bedding machining depth into a machining cutter table Tlist2= { …, Tn-2, Tn-1, Tn }, and obtaining each machining cutter in the machining cutter table to form a corresponding machining cutter path by referring to the machining process base information of the corresponding bedding.
Specifically, because the length of the tool in the machining tool library is rich, a plurality of machining tool tables (sets) larger than the maximum machining depth of the corresponding layer can be obtained in a comparison mode for selective use, and corresponding machining tool paths are formed.
Referring to fig. 1 to 5, further, an optimal machining tool method is selected according to the machining process of the corresponding cavity structure in the obtained machining tool table: and matching each processing cutter in the processing cutter table with the corresponding processing cutter path according to the concave cavity structure of the corresponding layer, performing simulated processing, and selecting the cutter with the shortest processing time as the processing cutter when the layer is actually used. Specifically, the plurality of tools in the obtained machining tool list are subjected to simulated machining according to corresponding layer structures, time is taken as a judgment basis, and the tool with the shortest machining time is selected as an actual machining tool, so that the improvement of the working efficiency in actual machining is facilitated.
